Methods and apparatuses for acknowledgement information with reduced redundancies. A method for a user equipment (UE) to provide a number of first hybrid automatic repeat request acknowledgement (HARQ-ACK) information bits includes determining a number of second HARQ-ACK information bits based on a HARQ-ACK codebook. The number of second HARQ-ACK information bits is larger than a first predetermined number and smaller than a second predetermined number. The first and second predetermined numbers are consecutive in a set of predetermined numbers. The method further includes determining the number of first HARQ-ACK information bits by appending a number of bits to the number of second HARQ-ACK information bits. The number of bits is equal to a difference between the second predetermined number and the number of second HARQ-ACK information bits. The method further includes transmitting an uplink channel with the number of first HARQ-ACK information bits.
